In aerospace engineering, the propellant mass fraction is the portion of a vehicle's mass which does not reach the destination, usually used as a measure of the vehicle's performance. In other words, the propellant mass fraction is the ratio between the propellant mass and the initial mass of the vehicle. In a spacecraft, the destination is ...
Some institutions differentiate between aeronautical and astronautical engineering. Graduate degrees are offered in advanced or specialty areas for the aerospace industry. A background in chemistry, physics, computer science and mathematics is important for students pursuing an aerospace engineering degree. [26]
Avionics engineering is similar, but deals with the electronics side of aerospace engineering. Aerospace materials – are materials, frequently metal alloys, that have either been developed for, or have come to prominence through, their use for aerospace purposes. These uses often require exceptional performance, strength or heat resistance ...
In aerospace engineering, mass ratio is a measure of the efficiency of a rocket.It describes how much more massive the vehicle is with propellant than without; that is, the ratio of the rocket's wet mass (vehicle plus contents plus propellant) to its dry mass (vehicle plus contents).
In aerospace engineering, payload fraction is a common term used to characterize the efficiency of a particular design. The payload fraction is the quotient of the payload mass and the total vehicle mass at the start of its journey. It is a function of specific impulse, propellant mass fraction and the structural coefficient. In aircraft ...
M = ship mass, not including the working mass. m = total mass ejected from the ship (working mass). The term working mass is used primarily in the aerospace field. In more "down to earth" examples, the working mass is typically provided by the Earth, which contains so much momentum in comparison to most vehicles that the amount it gains or ...
In China, for example, with the former specializing in nuclear power research (i.e. nuclear engineering), and the latter closer to engineering physics. [5] In some universities and their institutions, an engineering (or applied) physics major is a discipline or specialization within the scope of engineering science, or applied science. [6] [7 ...
The Canadian Engineering Accreditation Board is responsible for accrediting undergraduate aerospace engineering programs, [7] graduate study in aerospace engineering is also available at several Canadian post-secondary institutions, though Canadian post-graduate engineering programs do not require accreditation.
